Is it possible to make a tmpfs file system using xe command and make the vm run on it rather on HDD.This VM should not be slowed down by waiting for disks(This is what required).Can this be achieved using XEN server.Is there a better way of doing it?
This host is having only a single HDD and can not afford to add extra storage.

this is the best ever answer i have ever got from questions i have asked in server fault.i thought i will not get an answer for this question.I couldnt believe my eyes when i see a local storage named RAM in my storage.Thank you very much. to add a few.. parted command was not there,used fdisk instead.
